To all whom it nta/y concern:

Be it known that 1, HORATIO N. KILLSON, a citizen of the United States,residing at Elroy,in the county of Juneau and State of \Visconsin, haveinvented certain new and useful Improvements in Horseshoes and Calks, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

My invention relates to removable calks and horseshoe therefor; and theobjects of my invention are to provide a toe-call: of simple andcomparatively inexpensive construction which may be attached to anddetached from the shoe without removing the shoe from the hoof of ahorse, said calk being also adapted to be provided with a toecapintegral therewith for use as an abutnient against a portion of thefront of the hoof. I attain these objects by the constructionillustrated in the accompanying drawings, in which* Figure 1 is aperspective view of a toe-call; constructed in accordance with myinvention. Fig. 2 is a perspective view of a slightly-modified form ofthe calk in which the dovetailed retaining-tenon is made verticallylarger to constitute a toe-cap for the shoe. Fig. 3 is a perspectiveview of a horseshoe provided with a toe-call: constructed and secured tothe shoe in accordance with my invention. Fig. 4 is a longitudinalcentral section of the shoe and calk. V

In said drawings, A represents a horseshoe of any desired form, in thefront edge of which a groove a is cut that extends vertically throughoutthe body of the shoe. The rear edge of said groove is vertical; but theside edges a are beveled, so that the upper portion of the groove alongthe upper top face of the shoe is wider than the lower portion, but eachside of the groove is parallel with the long axis of the shoe.

The calk B consists of an angular body, the front part b of whichconstitutes the acute wearing portion of the calk, and the top 17constitutes a shelf to support the shoe and provides means to connectthe call: with said shoe, said shelf being substantially at right anglesto the front of the part b. On the top of the front portion of the shelfand over the wearing portion of the call: there is a dovetailed tenon bintegral therewith, the narrowest portion of which rests upon the shelfb The upper part of its front face is substantially equal to the widthof the front face of the wearing portion, but of less thickness fore andaft than the thickest part of the wearing portion 1), so that the curvedfront of the shoe will be weakened as little as possible by the groovea, cut into the toe of the shoe. The length of the dovetailed tenon b ina vertical direction is equal to the thickness of the shoe, in thegroove a of which it is to be inserted and seated by pushing it thereinfrom the front of the shoe in the direction of its long axis. Tosecurely retain the calk attached to the shoe, there is a perforation 0,made vertically through the shelf 19 of the calk, and a correspondingperforation cl in the long axis of the body of the shoe, but saidperforation dis screw-tapped. A stout screw or a short bolt e is made topass through the perforation c, and its threaded portion is made toenter into engagement with the screw-tapped perforation cl in the shoe,and these parts remain solidly united until the wearing portion of thecalk has been worn out and it is desired to rebuild or to sharpen thesame calk or to fasten a new one in position.

In Fig. 2 the vertical dovetailed tenon b has on top thereof andintegral therewith an arched cap 12 which constitutes a toe-cap, whichis generally made on the front of horseshoes to form a front stop forthe hoof of a horse and relieve the fastening-nails from strain.

I am aware that the top of toe-calks has been provided with a dovetailedtenon ex tended the whole length of the shelf; but said tenon extendsonly through the lower half of the shoe. 1 am also aware that the dovetailed tenon of toe-calks has been made to pass through the rear edge ofthe arched front of the shoe and has been provided with a toe cap andthat heel-calks have been provided with a narrow dovetailed tenon of awidth equal to half the width of each of said heels and inserted intogrooves in said heels; but the insertion of calks from the rear isobjectionable, because the striking (stumbling) blow of the shoe of ahorse while trotting is in a forward direction and the whole jar is uponthe fastening-screw, which therefore soon becomes loosened.

Having now fully described my invention, I claim 1. The combination of ahorseshoe having throughout the front thereof a groot'e having beveledsides parallel with the long axis-of the shoe, and an angular toe-call:having on its top shelf a dovetailed tenon part Way of saidshelf,andsubstantially of the same thickness and the same width as the face ofthe wearing portion of the calk, the height of said tenon being the sameas the thickness of the shoe, and inserted therein from the front, witha screw uniting said calk and shoe, substantially as described.

2. An angular toe-calk having a vertical wearing portion and aperforated horizontal shelf, and upon said shelf, over the wearingportion, a dovetailed tenon having a thickness and a width substantiallythe same as that of said wearing portion, and extended part way of saidshelf, the top of said tenon having its sides parallel with the sides ofthe shelf, substantially as described.

3. An angular toe-oalk having a vertical Wearing portion and aperforated horizontal shelf, and upon said shelf, over the wearingportion, a dovetailed tenon having a thickness and a width substantiallythe same as that of said Wearing portion and extended only part way ofsaid shelf, and on top of said tenon an arched toe-cap, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
